A cure for diseases caused by roundworms.
The 2015 Nobel Prize in Physiology or Medicine was awarded for discoveries of effective and safe therapies against infections caused by roundworms. Hundreds of millions of people in the tropics suffer from these diseases. For example, lymphatic filariasis, better known as elephantiasis, affects at least 100 million people. Helminthiasis, that is, diseases caused by such worms, is almost untreatable and much more difficult to treat than bacterial diseases. It is possible to find substances that kill the bacteria and do no harm to humans. Finding a substance that kills the worm without killing the person is very difficult.
Task: Identify the main problem that had to be solved in the creation of the cure.
1) the enormous swelling of the lower extremities typical of elephantiasis
2) the toxicity of existing antiparasitic drugs
